  • Each kit contains an installation tool and the quantity of inserts shown. One size per kit.
  • Also known as keenserts, keylocking inserts are available in mild steel and stainless steel.
  • Installation is by drilling out the old thread, countersinking, tapping new thread with a standard tap, screwing the insert until slightly below the surface, then tapping down the keys using the tool supplied and a hammer.
